RACK FOR TRACINGS.

Specification of Letters Patent.

Patented sept. 3, 1912.

y Application led November 20, 1911. Serial No. 661,359.

To all 'whom t may concern.'

Be it known that I, FRANK S. BAKER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Racks for Tracings, ofwhich the following is a specification.

It is a well known fact that the iling of blue prints, sketches ordrawings, or other such large and flexible sheets as are used inengineering and drafting ofiices gives rise to a great deal ofdiiiiculty. The sheets are thin and Hexible, and they have heretoforeusually been kept in drawers one on top of the other, or in envelopswhich are supported on end in'any suitable cabinet. The system ofkeeping them in drawers is productive of a great deal of difliculty,first, because of the large amount of space required to get at them, andsecond, since they rest one upon the other, it is difficult to extractthe bottom sheets from the drawer, and the drawers must therefore bemade very shallow, thus necessitating the use of a number of drawers tocontain them. Where the papers are inclosed in envelops, which envelopsare supported on one side inamore or less vertical position, it isdifficult to remove them, and they show a marked tendency when theenvelops are supported in the vertical position to sink down and wrinkleat one side. This of course is very undesirable, and it is likely toinjure expensive blue prints and drawings.

My invention, therefore, relates to improvements for storingA or holdingsuch sheets in a vertical position, and is more specifically directedtoward racks or drawers and associated means for supporting such sheets,and it has for one object to provide means whereby they may be suspendedeither separately or in groups, and whereby separate sheets may beinserted and removed without interfering with the sheets already inposition.

It is illustrated diagrammatically in one form in the accompanyingdrawings, wherein- Figure 1 is a section through the cabinet showing mydevice; Fig. 2 a part section through the cabinet showing a drawer inelevation; Fig. 3 a plan view of the drawer; Fig. A a section along theline 4.-4 of Fig. 2; Fig. 5 a detail plan view.

Like parts are indicated by like letters in all the gures.

A cabinet made up of the top A,back A1, d

base A2 and side walls A3 is provided with the parallel fixed tracks A4,A5, between which slide the floating track A, The drawer B, having thefront B1 extending preferably to the bottom of the cabinet, and thesides B3 and back Bt preferably. of lesser depth is provided with thetrack B5 in engagement with the fioating track AG. The removablesupporting bars C are preferably flat, and are held at the top of thedrawer in position by the cross rods C1, C2 which are supported in thesides of the drawer. The bars C are slotted at the rear end to fit overthe fixed cross bar C1 and are s sheets themselves and thus hold thesheets.

The hook D2 on the spring clip D2 engages the supporting bar C andsupports the sheets.

In the modified form of my invention indicated in Fig. 5, the rods E areprovided with the bentportions El bent in opposite directions andsubstantially parallel at either end, which portions engage the rods -C5and E2 at front and rear of the drawer.

It will be observed that since these portions are more or less offsetfrom the axis of the strip, they tend to hold the strip in a verticalposition.

It will be evident that while I have shown in my drawings an operativedevice, still many changes might be made in the size, shape andarrangement of parts without departing materially from the spirit of myinvention, and I wish therefore that my drawings may be regarded as in asense diagrammatical.

The use and operation of my invention are as follows: Blue prints,drawings, or any other such articles as it is desired to suspend may beassociated in groups or separately, as the ease may be, with anysuitable holding means. These means and the sheets themselves are thenengaged by the spring clips and the sprlng clips are hooked over theholding bars. These bars are held in position in the drawer either bythe cross rods as indicated or by means of the inclined portions andledges and any suitable number of groups or sheets may be supportedtherefrom. In the preferred form, it will be observed that the slots inthe rear ends of the bars and the perforations in the front ends whichare in e ngagement with the transverse rods hold the bars slidably in avertical position, thus 'keeping them on edge and enabling them to actas tension members. It will at once be observed that this structurepermits the use of lighter and thinner bars than would otherwise beneeded, thus permitting the use of an increased number of bars wit-houtany great weight.

I claim:

1. A cabinet comprising a drawer, a horizontally disposed fixedsupporting rod adjacent the back of the drawer at the top, ahorizontally disposed removable rod adjacent the front of the drawer atthe top, a ledge located beneath said removable rod, holding stripsslotted at one end and perforate at the other, mounted upon said rods.

2. A cabinet comprising a drawer, a horizontally disposed fixedsupporting rod adjacent the back of the drawer at the top, ahorizontally disposed removable rod adjacent the front of the drawer atthe top, a ledge located beneath said removable rod, holding stripsslotted at one end and perforate at the other, mounted upon said rods,the perforate end being engaged by the removable rod.

3. The combination with a drawer and horizontally disposed supportingstrips therein, of rigid supporting means at either endet said strips,perforations through one end of said strips and a removable rod locatedabove said supporting means and passing through said perforations tohold said strips in position.

t. The combination with a frame and horizontally disposed supportingstrips therein of supporting means upon which said strips rest, andremovable holding means located above said supporting means.
